Metal–metal-bonded compounds with low-valent metal centers have attracted much attention because they often exhibit specific reactivity towards small molecules and can afford novel adducts/complexes t
Transition-metal imido species are implicated as key intermediates in important transition-metal catalyzed transformations,e.g.C-H amination,olefin aziridation,dinitrogen functionalization,and have th
The precisely controlled polymerization of diene and styrene by using rare-earth metal catalysts will be reported.The pincer-type ligands stabilized rare-earth metal complexes catalyse the polymerizat
